Figs. 24, 25, 26, and 27 are views analogous to Fig. 4 and drawn for the purpose of illustrating picker and the pickershifter.

My improved hand lasting-machine consists of three principal parts-viz., the pincers, the tack-feeding mechanism, and the hammer.

The pincers consist of the upper jaw 25, having the handle 26 formed integral with its rear end, the lower jaw 27, pivotallymounted in operative position relative to 'said upper jaw, the lever 28, pivotally mounted in position to form a knuckle-joint with the rear end of said jaw 27, and the handle 29, connected to said lever 28. The plate 30 i's'placed against the'front side of the handle 26 and at the point where said handle joins the upper jaw 25, and the pins 31 and 32 are inserted through said plate and through said handle. Upon the lower face and near the forward end of the jaw 25 are teeth 33, and upon the upper face and forward end of the jaw 27 are similar teeth 34, and the jaw 27 is placed in position against the plate 30, with the teeth 34. in opposition tothe teeth 33, and the pin 35 is inserted through said plate and through the rear end of said jaw 27 in such a way that said jaw may turn upon said pin. In the rear end of the jaw 27 and upon the opposite side of the pin 35 from the teeth 34. is a recess 36, formed from the end surface of said jaw, the inner end of said recess being semicircular or rounded. The lever 28 has a circular'portion 37 upon its forward end which operates in said recess 36, and a neck which connects said circular portion with the body of said lever 28, thus formingaknuckle-joint between the lever 28 and the jaw 27 when said jaw is placed in position against the plate 30 and loosely mounted upon the pin 39. A plate 40 is placed in position against the rear faces of the handle 26, the rear end of the jaw 27, and the lever 2S, and said pins 3l, 32, 35, and 30 extend through said plate and hold it securely in position.

The foot l1 is lformed of a metal strap bent into the desired shape and consists ot' the portion l2, which is substantially horizontal, the portion byt3, which extends upwardly from the rear end of the portion l2 and has the notch 4t in its upper end, thus forming the projections 15 and 6, and the portion 47, which is bent upwardlyand backwardlyfrom the front end of the port-ion l2 to an angle of about twenty degrees and has the notch 'ULS Jformed in its upper end, thus forming the projections 40 and 50, which are bent upwardly and forwardly from the body of said portion 47. The foot thus formed is placed in position below the jaw 27 and somewhat behind said jaw, and the projections l5 and 9 are driven tightly into slots formed in the lower edge of the plate 30, while the projections 4G and 50 are driven into corresponding slots formed in the lower edge of the plate l0, thus holding said foot securely in position relative to the machine.

The handle 2O is of irregular shape and is connected to the rear end of the lever 2S, as shown in Fig. lO. An ear 5l extends backwardly from the center of the rear end of the lever 2S and is approximately one-third as wide as the body of said lever, thus forming the shoulders 52 and 5-3 at the junction of said ear with the body of said lever, and said shoulders are at approximately right angles to the top and bottom surfaces of said lever. The forward end of the handle 2f) is bifurcated to receive the ear 51, and a screw 5L is inserted from the rear side through the arm 55, then through the ear 5l and into the arm 56 to form a pivotal connection between the levers 2f) and 28. The upper forward corners of the arms 55 and 56 are rounded, as required to allow the handle 29 to bend upwardly from its normal position relative to the lever 2S, while the lower forward corners of said arms are square and lit against the shoulders 52 and 53, as required to prevent said handle from bending downwardly from its normal position relative to the lever 2S. The plates 30 and l0 are substantially the same size, the plate O being broken away in Fig. 2 to more clearly illustrate the construction between the plates. The arm 57 extends forwardly from the arm 5t' upon the front side of the plate 30 and on the opposite side of said plate from the lever 28 and to a point beyond the circular portion 3G of said lever. Said arm 57 is substantially straight and in alinement with the arms 55 and 5G, and from the front end of the arm 57 an arm 5S extends for wardly and upwardly and terminates in the rounded lower front surface 59. Near the center of the arm 57 is a screw-threaded aperture GO, and at the junction of the arm 57 with the arm 58 is a screw (il, screw-seated in said arms.

Extending upwardly from the rear end of the plate 40 is an arm 62, and extending forwardly from the upper side of said plate Ll0 is an arm G3. An arm (il extends upwardly from the forward end of the plate 30 to a point nearly on a level with the upper end of the arm G2. In the upper side of the jaw 25 and near its forward end is a dovetailed slot (55, extending transversely of said' jaw, and a tubular block GG has a dovetail upon its lower end which fits tightly within said slot (55, thus forming a connection between said block and said jaw. The inner face (S7 of the block 6G is substantially straight and joins the upper face of the jaw 25 at an angle of approximately forty-ve degrees and at such an angle that the handle 2G stands at approximately right angles to said block. A screw GS is inserted through the forward end of the arm 63 and screw-seated in said block G0, thus forming an additional support and brace for said block Gb. Extending upwardly from the upper end of the block 60 is a cylindrical portion G9, and a bore is formed through said cylindrical portion G9 and in a straight line through said block GG. The plunger 7l operates within the bore 70 and is of such size as that it will lit closely within said bore and operate freely. The stem 72 extends upwardly from the plunger 7l to a position some distance above the upper end of the cylindrical portion 69, and the upper end of said stem is screw-threaded. In the inner side of the cylindrical portion G0 is formed a slot 73, which extends from the upper end of the block GG nearly to the upper end of said cylindrical portion in a line radially relative to the center of the plunger 7l and parallel with the bore 70. The cap 7l is serew-seated upon the upper end of the cylindrical portion Uf), and an aperture is formed through said cap, which aperture serves as a bearing for the stem 72. The slot 73 extends upwardly partly through the cap 74. A packing-ring 75 is placed on top ot' the cap 7l around the stem 72, and a ynut 7G is screw-seated upon said stem above said packing-ring and is held securely in position by the jam-nut 77, which operates against the upper side of said nut 7G. rlhe stroke of the plunger 7l is regulated by manipulating the nuts 7G and 77, and the packing-ring 75 acts as a buffer for the nut In the lower end of the plunger 7l. is formed a bore extending partly through said plunger, in which is seated the driving-head or hammer 78. The block 75) is of such a size as that it will readily slide in the slot 73, and said block is secured to the plunger 7l by means of the screw SO, and the inner end of said screw 8O engages in a recess in the upper end of the hammer 7S and holds said hammer securely and removably in position. lrojecting from the inner and rear side of the block 79 is a pair of apertured ears 8].,between which is pivotally mounted the connecting-rod S2 ICO by means of a pin passing through said ears and through the lower end of said connectingrod.

A lever 84 (shown in detail in Fig. 20) is pivotally connected to the upper end of Vthe arm 64 by means of the bolt 85. A circular lug 86 projects from the front side of the upper end of thearm 64, and the bolt .85 is screw-seated or riveted throughsaid lug, as required to form a substantial and rigid support for said bolt, and the nut 87 is screwseated upon the rear end of said bolt, as required to hold said lever 84 removably in position. The upper end of the connectingrod 82 is pivotally connected to the forward end of the lever 84 by means of a screw 87, passing through said forward end and screwseated in the upper end of said connecting' rod. The rear end of the lever 84 terminates in the lug 88, the upper line of which is slightly concaved or curved downwardly relative to a straightl line from end toend through said lever. Projecting downwardly from the .rear portion of said lever 84 is a segmental or semicircular portion 89, ar-

ranged substantially concentric to the bolt 85, and ratchet-teeth are formed upon the;

forward 'and lower edgev of said segmental portion, said teeth pointing downwardly and backwardly. The pawl 91 (shown in Fig. 19) is pivotally mounted against the rear side of the arm 64 by means ofthe pin 92` and inV position to have its upperv end engage the teeth 90.l s

A spring93 has its rear end attached to the rear face of the arm 64, and saidspring extends upwardly and is coiled around the pin 2 and then extends downwardly, and its forward end is attached tothe lower end ofthe pawl 91, as required to have the tension of said spring exerted to force the lower end of said bolt backwardly, and thus hold the upper ,end of said bolt normally in engagement with said teeth 90. The lever 94 (shown in detail in Fig. 16)is in the form of a bell-crank, and upon the upper end and front side. of said lever is formed a lug 95,through which lug a bearing isformed for the pin 96, and said pin is riveted in positionl in said lug, and the roller 97' is rotatably mounted upon the end of said pin and againstthe rear side of said lever. In the lower forward end of the lever 94 is a segmental slot 98. A bolt 99 is fixed in position to project forwardly from the face of the arm 64 at a point approximately in the center of said arm, and the lever 94 is placed in position with the bolt 99 operating through the s lot 98. A connecting-rod 100 (shown in Fig. 15) is' placedin position to connect the arm 57 with the lever 94. The screw 101 is placed through the lower end of the connecting-rod 100 and is screw-seated in the aperture 60 in said ,arm 57. A circular` lug 102 projects backwardly from the upper end of said connecting-rod 100 and is yinserted in the aperture 103, which aperture is formed in the angle of the ,lever 94 and at approximately right angles relative to the pin 95 and the slot 98. The lower end 104 of the connecting-rod 100 is offset relative to the body of said connecting-rod, as required to bring the rear face of said body of said connecting-rod against the front face of the plate 30 and to bring said lower end .104 against the front face of the arm 57.

` The sliding block 105 (shown in detail in Fig. 21) is placed in position against the upper face of the handle 26, and the portion 106 of said block extends forwardly behind the arm 64 and has a recess 107 in its forward end, in which the lower end of the pawl 91 opcrates. The portion 108 of said block extends transversely behind the arm 64 and the portion v109 extends forwardly from the end of the portion 108 and outside of the arm 64and engages against the rear side of the connecting-rod 100, and the port-ion 110 of said block extends forwardly from the portion 109 and engages the outer surface of said connecting-rod 100.y The spring 111 has its rear end l112 iixed in the handle 26, and said spring extends upwardly and forms the coils 113, then downwardly to a position against the upper face of the arm 26, and the front end 114 of said spring engages the rear end of the block 105, as.' required to have its tension .exerted to normally hold said block forwardly. roller 97 normally engages above the portion 88 ofthe lever 84. When the operator brings the handles 26 and 29 together, the connecting-rod'lOO will pull backwardly and downwardly uponthe lever 94, thus depressing the portion 8S of the lever 84 and elevating the frontend of said lever, and thereby elevating the plunger 7l and the. hammer 78. As the front end of the lever 84 is elevated gradually .the pawl 91 will engage the teeth 90 and hold said lever in its elevated position. When the lever 94 tips backwardly, the upper end fof the connecting-rod 100,will also tip back-v wardly, and as said connecting-rod 100 is drawn. downwardly the sliding block 105 will be forced backwardly, and at the time the roller 97fleaves the portion 88 of the lever 84 the pawl 91 will be out of engagement-with the teethV 90, thus leaving the forward end of the lever 84 free to beagain depressed.

, .The tack-chute is constructed, as shown, in cross-section in Fig. 7 and consists of the upper guide-bar 115 and the lower guide-bars 116 and 117. The lower guide-bars 116 and 117vare arranged in parallel posit-ion in the same horizontal plane and a sufficient distance apart to allow the body portion of the tack to pass freely betweenvthem. The head of the tack rests upon the upper edges of said bars 116 and 117, and the guide-bar 115 is mounted directly above the head of the tack, the lower edge of said bar 115 being parallel with the upper edges of the bars 116 and .117 and said bar 115 occupying a vertical plane directly above the space between said-bars 116 andl17. The rear upper end of the bar 115 is attached tothe upper end of the arm The IOO

IIO

62 by means of the screw 11S, which screw is inserted from the rear side of said arm and is screwseated in the lug 119, projecting upwardly from said bar 115. The lug 119 is of such a thickness that the bar 115 does not come directly against arm 62 and is offset to bring it in the desired position. r1`he rear upper ends of the bars 116 and 117 are attached to the arm 62 by means of the rivet or screw 120, which rivet or screw passes through said arm 62 and then through the arms 121,which project downwardly from said bars 116 and 117, and said arms 121 are so formed as to bring said bars 116 and 117 in the desired position relative to the bar 115 and the desired distance apart relative to each other. The bars 115, 11b', and 117 extend forwardly and downwardlyat an angle of approximately forty-five degrees and lead the tacks to a point in the block 66 belowr the hammer 7S when said hammer is in its elevated position. The lower forward end of the bar 115 extends to the face of the block 66, and the lug or arm 122 extends into said block,as required to form a support for said forward end. rThe front side of the block 66 is cut away at its lower portion, as shown in Figs. 4, 5, and 6, and the front lower end of the bar 116 extends into said cut-away portion and is secured in position by means of the screw 123, (shown in Fig. 3,) which screw passes through said bar 116 and is screw-seated in said block 6G. The forward end of the bar 117 extends into the cut-away portion in said block 66, and a lug 124 extends into a recess in said block, as required to hold said bar in position. A strengthening-strip 125 is formed upon the upper edge of the bar 115 and extends around the bolt 87, as shown in Fig. 2. A leaf-spring 126 is attached at its forward end to the front face of the bar 117 and extends backwardly to a position beyond the upper end of said bar, and a pin 127 is xed to said spring near its free end, and said pin operates horizontally through openings 12S in said bars 116 and 117. A pin 129 is iixed to the free end of the spring 126 and extends horizontally across and near to the upper end of said bars 116 and 117. In feeding the tacks into the chute the lug 129 is operated to press the free end of the spring 126 away from the bai-117, and thus withdraw the pin 127 and allow the passage of the tacks down the chute. After the chute has been filled with tacks the lug 129 is released, allowing the pin 127 to return to its normal position, and thus preventing the tacks from passing backwardly out of said chute. The pin 127 is fixed through the upper end of the lug 130, which extends upwardly from the spring 126, the object being to get the pin 127 as near to the upper edges of the bars 116 and 117 as possible.

A rectangular aperture 131 is formed through the lower end of the bar 117, and an aperture 132 is formed through the bar 116 diagonally, said apertures 131 and 132 being substantially opposite each other. A leafspring 133 is secured to the rear side of the bar 116 by means of the rivets 134, and the free end of said spring extends through the aperture 132 to a point near the throat 135, which throat is a continuation of the bore through the ends of the bars 116 and 117 and is formed by concaving the adjacent faces of said bars. r1`he aperture 131 intersects the throat 135.

The leaf-spring 136 (shown in Fig. 13) has its lower end 137 bent outwardly at right angles to its body and secured to the surface 138 by means of a rivet or screw passing through the aperture 139 and into the bar 117. The surface 138 forms the lower wall of the aperture 131. rllhe body portion of the spring 136 is substantially vertical, and from the upper end of said body portion a curved spring-arm 140 extends to the free end of the spring 133, the free ends of said springs 133 and 140 meeting half-way between the adjacent faces of the bars 116 and 117 and near the throat 135, as shown in Fig. 6. As the tacks pass down the chute they are held in check by the springs 133 and 140 until forced between said springs by the manipulation of the machine.

In the front face of the upper jaw 25 is formed a slot 141, which slot is at right angies relative to the cylindrical portion 69 of the block 66, and the picker-bar 142 (shown in detail in Fig. 1S) is slidingly mounted in said slot, the straight face 143 of said bar en gaging the bottom or inner surface of the slot and the opposite face of said bar projecting outwardly from said jaw. rl`he portion 144 of said bar slides behind the plate 30, as i11- dieated in dotted lines in Fig. 1.

The picker proper, 145, is attached to the front end of the picker-bar and operates in the opening 131. The shipper-bar 146 (shown in detail in Fig. 22) has a screw-threaded pin 147 projecting backwardly from near its upper end, which pin is inserted through the lever S4 at a point approximately half-way between the screw 87 and the bolt 85, and a nut 148 is screw-seated upon the rear end of said pin and against the rear surface of said lever S4 as required to form a pivotal connection between said lever S4 and the shipper-bar 146. The lower end 149 of the shipper-bar 146 is wedge-shaped, said wedge being formed by bifureating said lower end and bending one of the parts backwardly and the other one forwardly. The sl1ipper-bar 146 operates close to the front face of the jaw 25 and in contact with the front edge of the plate 30, and a recess 150 is formed in the lower front corner of said plate to receive the arm 151 of said shipper-bar when said bar is in its lowest position. The bar 146 is vertically reciprocated by the operation of the lever 84, and the arm 152 of said bar engages the shoulder 153 upon the picker-- bar 142, and when the bar 146 is elevated the arm 151, engaging the edge of the plate 30, will be forced forwardly, and the arm IOO IIO

. 152, engaging the shoulder 153, will force the picker-bar 142 forwardly. A perforated ear 154 is formed by bending the 'upper end of the bar 146 forwardly. A screw-eye '155 is inserted upwardly through 1 the aperture in said ear and is held adj ustably in position by the nut 156. A" retractile coil-spring 157 is connected to the eye 155, and the lower end of said spring engages the screw 61 in the arm 57. A retractile coil-spring 158 engages the pin 99, which projects from the arm 64 and upon which the lever 94 operates, and the upper end of said spring engages the pin 159, which pin is rigidly xed in the upper part of the lever 94, said spring operating to swing. said lever forwardly and upwardly. A spring 160 is secured to the shipper-bar 146 and extends forwardly, forming the coil 161, and then downwardly, and itslower end 162 operates through the aperture 163 in the picker-bar 142.l The springy V160 is attached to the bar 146 by means of the plate 164, as shown in Fig. 22. The end 162 of the spring 160 is reciprocated throughthe aperture 163 by the reciprocatory mot-ion of the bar 146, and the tension of said spring operates to return the picker-bar 142 to its normal position after said picker-bar has lbeen forced forward by the operation of said bar 146. Projecting outwardly from the center of the picker-bar 142 is an arm or lug 165, which engages the end of the arm 58. The upper corner 166 of the lug 165 is beveled. The picker 145 oper-A ates below the surface which forms the upper wall of the aperture 131, and said picker 145 is carried upon the inner end of the arm 167and has the concaved front face 168, which face is vertical or parallel with the line of travel of the hammer. Theupper end of the picker 145 is substantially on a level with the upper. face of the 4picker-bar 142, while its lower end 169 extends some distance below said bar. In forcing a tack forwardvthe picker 145 operates against the inner surface of the bar 116, and said picker forces the tack between the points of the springs 133 and 140, and said picker also passes between said points.' The arm 167 extends through. the opening 131 immediately. above the spring 140. The lugs 170 andy 171 are formed, respectively, upon the lower and upper faces and near the forward end of the picker-bar 142 and extend diagonally across said faces, the inner ends of said lugs being nearer the end of the'bar than theouter ends.

The picker-shifter 172 (shown in Figs. 8

and 9) is seated in a rectangular recess in the block 66 in position directly above the opening13l and is mounted upon the pivot 173, which extends through the upper end of said shifter and into said block 66. The pickershifter 172 consists of the perforated ear 174, through which the pivot 173 operates, and the diagonal lugs 1 75 and 176, which lugs are connected by the circular orv segmental bar 177, said bar also being attached to or formed integral with the ear 1'72. The lugs 175 and 176 are arranged upon diagonal lines/corre-l sponding to the lugs 170 and 171 and a suiiicient distance apart to allow the arm 167 to pass between them. Between the lugs 175 and 176 and the bar 177 is a space 178, through which the end of the picker-bar 142 operates. The inner ends of the lugs 175 and 176 are mormally held in a position in a line with the front surface of the bar 117 and in position to be engaged by the lugs 170 and 171.A The spring 179 is held in position against the block 66 by means of the screw 180, and the free endof said spring engages against the outer edge and lower end of the ear 172 as required to hold the shifter in its normal position. When the picker-bar 142 is forced forwardly, the lugs 170 and 171i engage the inner faces of the lugs 17 5 and 17 6 and press them outwardly against the tension of the spring 179. When the picker returns to its normal position, said lugs 17 O and 171 engage the outer surface of said lugs 17 5 and 17 6 and press the forward end of the picker-bar 142 outwardly, thus carrying the picker 145 backwardly upon the outside of the spring 140.

The tack-holder 181, which is shown in detail in Fig. 12, consists of the two mating parts 182 and 183, which parts are substantially alike, with the exception that one is right-handed andl the other is left-handed. The upper ends 184 of the parts 182 and 183 are inserted in an.v aperture in the block 66 and are held in 'position by being engaged by the inner end of the screw 180. The portions 185 of said parts extend downwardly outside of the block 66 to a point below the lower end of said block. The blocks 186 are attached to the lower ends of said portions 185 in horizontal alinement with eachother and side by side, and the meeting faces of said blocks are concaved, as required to form a vertical opening 187, which opening is substantially circular in cross-section andis larger in diameter at its upper end than at itsylower end, and said opening is in vertical alinement with the throat 135 .and with the bore 70. The portions 185 act as springs to hold the blocks 186 yieldingly together.

Assuming that the machine has been loaded with tacks and the parts are in position for operation, the operator grasps the handles 26 and 29 in his right hand, places the edge of the leather betweenthe jaws 25 and 27 and places the foot 41 upon the last. It is neces- IOO IIO

sary that thejaws grip the leather before the f Vreason for this being that the spring 157,

l "il I- I which may be termed the weight, is pulling upwardly on the end of thc arm 57, and as said arm 57 is fulcrumed to the rear end of the lever 2S said rear end of said lever is likewise pulled upwardly. The shoulders at the forward ends of the arms 55 and 56 abut against the shoulders formed at the rear end of the ear 51, and said shoulders are so constructed as to make a knife-blade joint between the lever 28 and the handle 26, which joint allows said handle to breakin one direction only and Ithat direction being upwardly. The lever 2S fuleruming upon the pivot 39, said handle 20 will by reason of its being connected to said lever 2S fulcrum upon said pivot 3!l,and as said handle is moved upwardly toward the handle 26 the forward end of the lever 2S will operate in the socket formed in the rear end of the jaw 27 and the forward toothed end of said jaw will be thrown upwardly to grip the leather against the teeth 33 of the jaw Then the leather is gripped between said jaws and the jaw 27 can move no farther, the i'ulerum-point of the handle 29 will be transferred from the pivot 39 to the pivot 51, the lever 2S having ceased to move with the stopping of the jaw 27. The tension or resistance of the spring 157 is during this movement constantly increasing, for the reason that the end of the arm 57, to which said spring is attached, is moving downwardly and expanding said spring. rlhis operation also pulls downwardly upon the connectingrod 100, causing the roller 67 to engage the projection SS upon the rear end of the lever 81, and as said rear end of the lever is depressed the forward end of said lever is elevated, and consequently the hammer is elevated. Then the hammer has reached its uppermost position, the roller 97 will slip from the projection SS and allow the hammer to rebound to its normal position bythe tension of the spring 157,which springis pulling downwardly. The elevation of the forward end of the lever S1, as described,will cause the Shipper-bar 116 to slide upwardly and force the picker-bar 112 forwardly, thus forcing the tack which is in front of the picker 115 into the throat The end 56 of the arm 5S willengage against the rear side of the lug 165 and will hold the pieker-bar112 in its forward position, which is the position shown in Fig. 6, until the hammer descends and drives the tack. lVhile the picker 115 is in the position shown in Fig. 6 it closes the open side of the throat 135 and prevents the tack from turning in said throat. lVhen the tack passes into the throat 135, it will drop downwardly into the tack-holder 181, and the conical shape of the opening through said tack-holder will act as a means of centering said tack relative te the hammer and will hold said tack in position to be driven. XVhen the hammer descends, the head of the tack and the face of the hammer will spread the blocks 186 between which the tack is held and allow said tack to pass downwardly through the leather and into the last. lVhen the grip upon the handles 26 and 29 is relaxed, the jaws will again open, the roller S7 will return to its position above the projection SS, the picker-bar will return to its normal position, the forward tack will pass to its normal position between the free ends of the springs 133 and 110, the picker in returning to its normal position will pass outside of the spring 110, and thus the point 16S will be brought behind the forward tack, which is between the points of the springs 133 and 110 and is in position when the machine is again operated to press said tack forwardly into position to be driven. lVhen the shipper-bar 116 is elevated, the end 162 of the spring 160 reciproeates through the opening 163 in the picker-bar 11-2, but the tension of said spring is exerted against said pickerbar at all times. XVhen the handles 26 and 26 are pressed together only a part of their limit of motion, the jaws 25 and 27 are brought together and the hammer is partially elevated and the pawl 61 holds said hammer in said elevated position. lf the grip upon the handles be now relaxed, the jaws will open without driving the tack, although the tack maybe in position in the tack-holder to be driven The first part of the motion of the handle 29 toward the handle 26 will eiose the jaws, but it is the latter part of said motion which releases the hammer. Should the operator fail to apply the final grip to the handles, which will elevate the hammer to its highest position and release it and allow it to rebound, the tack will remain in the tackholder until the next operation. After the hammer has been released by the slipping of the roller 97 from the projection SS should the operator fail to sufficiently relax his grip to allow the handles to spread apart far enough to allow said roller to return to its position above said projection SS the picker-bar 142 will not be operated because the shipper-bar 1&6 will not be operated, and then the forward end 56 of the arm 5S will strike the beveled corner 166 of the lug 1.65 upon said picker-bar and will slip or glance outwardly over said lug and the picker-bar will not be operated to feed a tack. This is an important feature, because if the picker-bar was operated by every motion of the handles, whether or not the hammer was elevated, the tacks would become clogged in the throat 135, but by the construction described the tacks will not be fed to the throat 135 faster than they are driven by the operation of the ham m er.

Vhile my improved hand lasting-machine contains all the mechanism required for the purposes described, it is not teo heavy to be operated easily and its operation will prove very efficient and satisfactory.
